And solve low efficiency when Conventional mud motor drives drilling work, pollution weight, the easily damaged electric leakage of signal wire and probe storehouse processing
The inconvenient technical problem of complex process, probe replacement.
Technical solution used by the utility model is as follows:
A kind of bilayer orientation drill, including guiding outer bar, the guiding outer bar inside is hollow tubular structures, is oriented in outer bar
Equipped with the guiding interior bar being overlapped with its axis, it is connected with seal pipe thereon, to being connected to ball in the circumferential end surfaces of seal pipe side
Bearing, ball bearing are nested in guiding interior bar；One end of guiding interior bar is threadedly coupled with tricone bit, and other end stretching is led
It is connect outside to outer bar with driving device；It is oriented on the inner wall of outer bar and is welded with bottom case in parallel, it is dismountable on bottom case
It is equipped with its closed warehouse lid, forms the cylindrical cavity of sealing between warehouse lid and bottom case.
Its further technical solution is:
The equal length of warehouse lid and bottom case, and it is less than the length of guiding outer bar.
The center of circle of cavity on same cross section and the line for being oriented to the interior bar center of circle are overlapped with the central axis of guiding interior bar.
The warehouse lid upper surface is provided with waist type groove.
Sealant is filled in seal pipe.
Sealing ring is equipped between the outer wall and guiding outer bar inner wall of seal pipe.
Bottom case is removably connect by bolt with warehouse lid.
The part that guiding interior bar is located at seal pipe side is solid construction, and the part positioned at the seal pipe other side is hollow knot
Structure.
The inner wall of the hollow structure of the guiding interior bar is equipped with the internal screw thread connecting with tricone bit.
The driving device is hydraulic motor.
The beneficial effects of the utility model are as follows:
The utility model is compact-sized, reasonable, easy to operate, and upper casing is connect by bolt with bottom case, by upper casing detachable
It is mounted in guiding outer bar, convenient for machining, conveniently from side in the dismounting for carrying out probe；Probe is convenient in the setting of waist type groove
The transmission of signal；It is connected between guiding interior bar and guiding outer bar at one end through ball bearing, the other end is respectively by independent dynamic
The driving of power device, is not necessarily to practical mud motor and signal wire, improves the operating performance of equipment and the stability of operation.
